don't consume a sink, return a source instead. the only reason to not do
this is a very slight reduction in dynamic allocations, but since we are
going to *at least* do disk io that will not be a lot of overhead anyway

The lock usage was obviously wrong so it was entirely serialized. This
has the predicted speedups, the only question is whether it is sound
because it's exposing a bunch of new code to actual concurrency.
I did audit all the stores' queryPathInfoUncached implementations and
they all look *intended* to be thread safe, but whether that is actually
sound or not: lol lmao. I am highly confident in the s3 one because it
is calling s3 sdk methods that are thread safe and has no actual state.
Others are using Pool and look to be *supposed* to be thread safe, but
unsure if they actually are.

This seems to fix a use of stack after return.

We don't want to deal with these at all, let's stop doing so.

This:
- Consistently returns `nullptr` for a non-existent
store path, instead of a mix of `nullptr` and
throwing exceptions.
- If a store returns "bad" store paths in response
to a request (e.g. incorrect hash or name), don't
cache this result. This removes some duplication
of code at the cache-access layer of queryPathInfo()
checking this, and allows us to provide more
specific errors.
Part of #270.

Here's my guide so far:
$ rg '((?!(recursive).*) Nix
(?!(daemon|store|expression|Rocks!|Packages|language|derivation|archive|account|user|sandbox|flake).*))'
-g '!doc/' --pcre2
All items from this query have been tackled. For the documentation side:
that's for https://git.lix.systems/lix-project/lix/issues/162.
Additionally, all remaining references to github.com/NixOS/nix which
were not relevant were also replaced.

it's no longer used. it really shouldn't have existed this long since it
was just a mashup of both std::promise and std::packaged_task in a shape
that makes composition unnecessarily difficult. all but a single case of
Callback pattern calls were fully synchronous anyway, and even this sole
outlier was by far not important enough to justify the extra complexity.

When /nix/var (or, more precisely, NIX_STATE_DIR) does not exist at all,
Lix falls back to creating an adhoc chroot store in XDG_DATA_HOME.
b247ef72d[1] changed the way Store classes are initialized, and in the
migration, a `params2` was accidentally changed to `params`. This commit
restores the correct behavior, and in lieu of a single *character* fix,
this commit also changes the variable name to something more reasonable.
Fixes #274.

n.b., this code might deserve some more looking at anyway. this fallback
store creation throws away *all* Store params passed to
openFromNonUri() in favor of an entirely new set which only contains
the `root` param, which may or may not be the correct behavior

This creates new subclasses of LocalStore for each OS to include
platform-specific functionality. Currently this just includes garbage
collector roots but it could be extended to sandboxing as well.
In order to make sure that the generic LocalStore is not accidentally
constructed, its constructor is protected. A Fallback is provided which
implements no functionality except constructors.

This is analogous to that for experimental settings and flags that we
have also added as of late.

obsidiansystems/queryPartialDerivationOutputMap-evalStore
Give `queryPartialDerivationOutputMap` an `evalStore` parameter
|
|
This makes it more useful. In general, the derivation will be in one
store, and the realisation info is in another.
This also helps us avoid duplication. See how `resolveDerivedPath` is
now simpler because it uses `queryPartialDerivationOutputMap`. In #8369
we get more flavors of derived path, and need more code to resolve them
all, and this problem only gets worse.
The fact that we need a new method to deal with the multiple dispatch is
unfortunate, but this generally relates to the fact that `Store` is a
sub-par interface, too bulky/unwieldy and conflating separate concerns.
Solving that is out of scope of this PR.
This is part of the RFC 92 work. See tracking issue #6316

Whereas `ContentAddressWithReferences` is a sum type complex because different
varieties support different notions of reference, and
`ContentAddressMethod` is a nested enum to support that,
`ContentAddress` can be a simple pair of a method and hash.
`ContentAddress` does not need to be a sum type on the outside because
the choice of method doesn't effect what type of hashes we can use.

The code is not local-store-specific, so we should share it with all
stores. More uniform behavior is better, and a less store-specific
functionality is more maintainable.
This fixes a FIXME added in f73d911628 by @edolstra himself.

We weren't because this ancient PR predated it!
This is actually a new version of the pattern which addresses some
issues identified in #7479.
|
|
Also improve content-address.hh API docs.
|
|
This is needed in subsequent commits to allow the settings and CLI args
infrastructure itself to read this setting.

Display progress when running copyPaths (nix copy)
|
|
`nix copy` operations did not show progress. This is quite confusing.
Add a `progressSink` which displays the progress during `copyPaths`,
pretty much copied from `copyStorePath`.

Currently the valid key is only present when the path is invalid, which
makes checking path validity more complex than it should be. With this
change, the valid key can always be used to check if a path is valid

With the switch to C++20, the rules became more strict, and we can no
longer initialize base classes. Make them comments instead.
(BTW
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p2287r1.html
this offers some new syntax for this use-case. Hopefully this will be
adopted and we can eventually use it.)

Avoid needless work and throwing away invariants.
These conversions date back to when `StorePath` was in Rust and there
were issues with it missing utility methods.
|
|
We don't need it yet, we can add it back later.
|
|
This change can wait for another PR.
